摘要： Provided is a 4× framer/deframer module for PCI-Express and a framer/deframer device using the same. In the PCI-Express for high-rate data processing, delimiter and pad processing, and 4× framer shifting and arrangement/reverse arrangement for framing/deframing a frame format are performed to achieve a structure that facilitates reconfiguration and expansion, for example, a pipeline structure, so that the 4× framer/deframer module can operate without delay within a 250 MHz clock even when expansion to 32× is made.

摘要： A method and an apparatus for checking a pipelined parallel cyclic redundancy is disclosed. In accordance with the method and the apparatus of the present invention, after an entire CRC (cyclic redundancy check) logic is divided into a feedback portion and an input data portion, the input data portion is divided using a pipelined structure such that the input data portion is designed to have the pipelined structure based on an algorithm that maintains a logic level of each stage to be lower than that of the feedback portion and an algorithm that optimizes a size of a register inserted during the division to improve a speed thereof and to detect an error of a received data in a high speed data communication apparatus.

摘要： A method for adjusting backlight brightness for an image display device whose backlights are arranged in an M×N, 2-dimensional array, and an apparatus for realizing this are provided. The method comprises a full search step determining the brightness adjustment value for each of the M×N image blocks corresponding to the backlights for the entire input image and selecting a reference block; a partial search step determining the brightness adjustment value for the selected reference block and surrounding blocks thereof for the image frame inputted following the full search step and reselecting a reference block based on the brightness adjustment value of the previous reference block and surrounding blocks thereof; and an adjustment step adjusting brightness of the backlights in accordance with the brightness adjustment value for each block as determined by the full search step and/or partial search step. In accordance with the present invention, it is possible to increase the speed of image analysis for a display that uses backlights. Likewise, controlling the backlight using the characteristics of the analyzed image enables reducing power consumption and increasing the contrast ratio by applying backlight brightness according to the characteristics of the image.
